SPECIFICATION
Dry-shaving apparatus e invention relates to a dry-shaving apparatus comprising a shear plate with hair-entry apertures, a cutting member which is rotatable relative to the shear plate, and a coupling spindle which is rotationally coupled at one end to the cutting member and at the other end to a drive element of a drive mechanism of the apparatus.
Such a shaving apparatus is known from, for example, United Kingdom Patent Specifi- cation No. 1,388,520. In this known appa- ratus the coupling spindle is formed at its end remote from the cutting member with a square flange which engages in a recess of corresponding shape in the drive element to provide the rotational coupling between this element and the coupling spindle. The flange is retained in the recess by means of a ring which clips on the drive element and closes the recess. The coupling spindle is thereby coupled to the drive element in the axial direction also.
According to the present invention there is provided a dry-shaving apparatus comprising a shear plate with hair-entry apertures, a cut ting member which is rotatable relative to the shear plate. and a coupling spindle which is rotationally coupled at one end to the cutting member and at the other end to a drive element of a drive mechanism of the appa ratus, wherein the coupling spindle is also coupled to the drive element in the axial direction by integral portions of the drive element which are distributed about the rota tional axis of this element and which project radially inwardly over the periphery of a 105 flange on said other end of the coupling spindle, said projecting portions of the drive element being formed on parts of this element which are elastically deflexible radially of the element. 1 An embodiment of the invention will now be described with reference to the accompa nying drawings in which Figure 1 is a front elevation of a dry shaving apparatus according to an embodi- 115 ment of the invention having three shaving haads.
Figure 2 is a side elevation of the shaving apparatus of Fig. 1 with one of the shaving heads shown in cross-section, the section be ing taken on the line 1111 in Fig. 1, Figure 3 is an enlarged axial sectional view of the rotary cutting member and coupling spindle of one of the shaving heads and an associated gear wheel of the drive mecha nism, and Figure 4 is a sectional view taken on the line IV-IV in Fig. 3.
The shaving apparatus shown in Figs. 1 and 2 comprises a housing 1 on which is 130 mounted a shear-plate holder 2 for three stationary shear plates 3. The shear plates 3 have hair-entry apertures 4. A rotary cutting member 5 is situated on the inner side of each shear plate 3 for cooperation therewith in known manner.
The cutting members are rotated relative to the shear plates by a drive mechanism comprising an electric motor 10, to which the cutting members are each coupled by an associated coupling spindle 6 and gear wheel 7 and a gear wheel 8 fixed on the motor shaft 9. The gear wheels 7 are each rotatably journalled on an associated spindle 11 which is secured in a mounting plate 12. Each gear wheel 7 is provided with a hollow hub 13, the interior of which forms a cavity 14 which accommodates a flange 15 on one end of the associated coupling spindle 6. A coil spring 16, which for the greater part is disposed in an axial bore in the coupling spindle 6 and which is compressed between the coupling spindle and the gear wheel 7, exerts a force on the coupling spindle in the direction of the associated cutting member 5. This force is transmitted to the cutting member 5 by the coupling spindle 6 and via the cutting member to the associated shear plate 3, a flange 17 on which is thereby pressed against the shear plate holder 2. During use of the shaving apparatus, the shear plates 3, together with the associated cutting members 5 and coupling spindles 6, can be pressed inwards against the action of the springs 16 under the pressure with which the shear plates are held against the user's skin.
All three cutting members 5 are coupled to the drive motor 10 in the above manner, the three gear wheels 7 meshing with the single centrally disposed gear wheel 8 on the motor shaft 9.
As is shown in Figs. 3 and 4, three ribs 18 are formed on the wall 19 of the cavity 14 in the hub 13 of each gear wheel 7. The ribs 18 extend axially of the cavity 14 and project radially inwards from the wall 19 thereof and are equispaced about the axis of rotation 23 of the gear wheel 7. The flange 15 of each coupling spindle 6 is formed in its periphery with three equispaced recesses 20, a side wall 21 of each of which engages with a corresponding one of the ribs 18 in the hub 13 of the associated gear wheel 7. Thus a threepoint coupling is obtained between the coupling spindle 6 and the gear wheel 7 to transmit the rotary movement of the gear wheel to the coupling spindle 6 and the gear wheel 7 to transmit the rotary movement of the gear wheel to the coupling spindle. This coupling, which is described and claimed in the specification of the Applicants' co-pending application no. 45922/78 allows the coupling spindle to be tilted relative to the gear wheel 7, i.e., to assume a position, such as that shown in Fig. 3, in which the axis of
GB2057955A 2 rotation 22 of the coupling spindle 6 is neither parallel nor coincident with the axis of rotation 23 of the gear wheel 7.
On the lip of the hub 13 of each gear wheel 7 are three radially inwardly directed projections 24 which project over the periphery of the flange 15 of the associated coupling spindle 6 to retain the flange in the cavity 14 in the hub 13, so that the coupling spindle is also coupled to the gear wheel 7 in the axial direction. On opposite sides of each projection 24 the hub is formed with axially extending slits 25 so that a wall portion 26 of the hub which is situated between the slits and which is integral with the projection 24 can deflect elastically in a radial direction. This enables the end of the coupling spindle 6 on which the flange 15 is formed to be inserted in or removed from the cavity 14 in a simple manner. Assembly is effected simply by pressing the flange 15 into the hub of the gear wheel 7. Withdrawal of the flange can be effected with the aid of a simple tool.
At its end remote from the flange 15 each coupling spindle 6 is formed with axially projecting coupling members 27 which engage in coupling apertures 29 in a hub portion 28 of the respective cutting member 5 to form therewith a coupling for transmitting the ro- tary movement of the coupling spindle to the cutting member. This coupling also is described and claimed in the specification of the Applicants' co-pending application no. 45922/78 and requires no further descrip- tion in the present specification since it forms no part of the present invention.
